1 is a diagram for explaining the operation of a ship control system according to an embodiment.

A smart ship is a next-generation digital ship that applies information and communication technology (ICT), and is a versatile ship that promotes economical and safe operation as well as an autonomous navigation system. Smart ship technologies include Autonomous Navigation System (ANS), Integrated Maritime Information Technology (IMIT), and Automatic Identification System (AIS) for autonomous operation. Technology is a representative example.

In particular, AIS (Automatic Identification System) is a state-of-the-art device that provides navigation information such as the ship's position, course, and speed in real time. It provides information such as the own ship's course, speed, and position to other ships to prevent collisions. It is a navigation equipment that can search basic navigation information in real time.

A sailing vessel can only know what type of vessel and name of other vessel sailing around it through the binoculars installed on the bridge, but cannot know the course or speed, and what is the destination or cargo information. Ship information such as the battlefield/width/depth of the enemy ship is unknown. AIS is an electronic device that omits these procedures and helps you easily obtain information about ships sailing around the ship, establish sailing plans, and change them according to the situation.

According to one example, as shown in FIG. 1, the AIS receiver 20 installed in the port may receive AIS information of the ship 10 from the ship 10 equipped with AIS and transmit it to the server device 100. Here, the server device 100 may be a server managed by the port management office (control center). In this case, the operating station can store the transmitted data and also transmit it back to the Vessel Traffic Service (VTS) and the integrated computer center. Data stored in the integrated computer center is transmitted to the linked server, and then ship operation information can be transmitted to the Ministry of Oceans and Fisheries' comprehensive situation room and each related organization. Accordingly, the server device 100 can be implemented as a server managed by various organizations such as maritime traffic control, the Ministry of Oceans and Fisheries comprehensive situation room, as well as the operating station (control center).

Below, various embodiments for preventing collisions with major facilities located in ports when berthing/unloading a ship using this AIS technology will be described.

Figure 2 is a block diagram showing the configuration of the server device 100 according to an embodiment.

According to FIG. 2, the server device 100 may include a communication interface 110, a memory 120, and a processor 130. For example, the server device 100 may be implemented as a cloud server, but is not limited to this.

The communication interface 110 may support various communication methods depending on the implementation example of the server device 100.

For example, the communication interface 110 may be used for mobile communication such as LTE, 5G, Bluetooth, AP-based Wi-Fi (Wireless LAN network), Zigbee, and wired/wireless LAN (Local Area Network). ), WAN (Wide Area Network), Ethernet, IEEE 1394, HDMI (High-Definition Multimedia Interface), USB (Universal Serial Bus), MHL (Mobile High-Definition Link), AES/EBU (Audio Engineering Society/ You can communicate with external devices, external storage media (e.g. USB memory), external servers (e.g. cloud servers), etc. through communication methods such as European Broadcasting Union, Optical, Coaxial, etc. You can.

Specifically, the communication interface 110 can communicate with an external device. For example, the communication interface 110 may receive data from an external device and transmit data to the external device. Here, the external device may be implemented as a ship, user terminal, external server, etc., but is not limited thereto.

The memory 120 can store various data related to the operation and function of the server device 100. Additionally, at least one instruction for driving the server device 100 may be stored in the memory 120. Additionally, various software programs or applications for operating the server device 100 may be stored in the memory 120 . Additionally, various software modules for operating the server device 100 may be stored in the memory 120.

In this case, the memory 120 may be implemented as non-volatile memory, volatile memory, flash-memory, hard disk drive (HDD), or solid state drive (SSD).

The processor 130 generally controls the operation of the server device 100. Specifically, the processor 130 is connected to each component of the server device 100 and can generally control the operation of the server device 100. For example, the processor 130 may be connected to the communication interface 110 and the memory 120 to control the server device 100. The processor 130 can control hardware or software components connected to the processor 130 by running an operating system or application program, and can perform various data processing and calculations. Additionally, the processor 130 may load and process commands or data received from at least one of the other components into volatile memory and store various data in non-volatile memory.

According to one example, the processor 130 may include a digital signal processor (DSP), a microprocessor, a time controller (TCON), a central processing unit (CPU), and a micro controller unit (MCU). , a micro processing unit (MPU), a controller, an application processor (AP), or a communication processor (CP), or an ARM processor, or may be defined by those terms. Additionally, the processor 130 may be implemented as a system on chip (SoC) with a built-in processing algorithm, large scale integration (LSI), or may be implemented in the form of a field programmable gate array (FPGA).

Figure 3 is a flowchart for explaining a method of controlling a server device according to an embodiment.

According to an embodiment shown in FIG. 3, the processor 130 divides the ship's AIS information received from the AIS (Automatic Identification System) device installed at the port by time and MMSI (Maritime Mobile Service Identity) and stores it in memory 120. ) can be saved (S310). Here, the AIS device installed in the port may be an AIS receiving device implemented to receive AIS information of the ship from the ship.

According to one example, the AIS information of a ship includes ship location information (e.g., latitude and longitude information), speed information, ground speed information, ground direction information, dynamic information of heading information, and ship name, specifications, port entry and departure time, odd number, It may include navigation information such as port arrival and departure times, but is not limited to this and may include various information that can be collected through AIS technology. AIS can automatically transmit information once every few to tens of seconds, and may include, for example, Terrestrial AIS data and Satellite AIS data.

MMSI (Maritime Mobile Service Identity) is a code used to uniquely identify ship stations, maritime stations, group calls, etc., and may consist of, for example, 9 numbers. For example, the first 3 digits are the Maritime Identification Code (MID) indicating the country or region to which the ship belongs, and if the last 3 digits end in 000, the ship is on an international voyage. If the last 3 digits end in 00, the ship is on a domestic voyage. When finished, it can mean a vessel engaged in domestic communications services.

Subsequently, the processor 130 may identify whether there is a possibility of a ship colliding based on the AIS data stored in the memory 120 and the location information of at least one facility located in the port (S320). For example, location information of a plurality of major facilities located in a port may be previously stored in the memory 120.

Afterwards, the processor 130 may transmit information about the possibility of a collision according to the identification result to at least one of the ship or the user terminal through the communication interface 110. Here, the user terminal may be implemented as a variety of devices that are connected to the server device 100 and have a display. For example, a user terminal may be implemented as a smart phone, tablet, PC, smart TV, monitor, smart TV, signage, etc., but is not limited to this and may be implemented as a large format display (LFD), digital signage, etc. ), DID (Digital Information Display), video wall, projector display, etc. can be implemented as various types of devices with display functions.

According to one example, the processor 130 may track the movement of the ship and collect information about the ship's operation using the ship's AIS information. AIS can be implemented as a device that integrates a digital VHF radio transceiver, a positioning system such as GPS, and other electronic navigation sensors such as a gyrosensor. Vessels equipped with AIS transceivers can be tracked from a coastal base station if they are on the coast, and can be tracked through satellite communication if they leave a specific area. For communication between ships and coastal base stations, two VHF frequency channels, 87CH (161.975MHz) and 88CH (162.025MHz), within the maritime mobile frequency band are used, and each channel has a transmission rate of 9,600bps. According to one example, the AIS device consists of two independent receivers and one transmitter, and the receiver can receive information from two channels simultaneously, but the number of receivers and transmitters is not limited to this.

According to one example, the processor 130 may identify whether there is a possibility of a ship colliding based on the AIS data and port map information stored in the memory 120 and transmit it to at least one of the ship or the user terminal through the communication interface 110. there is. In this case, at least one of the ship or the user terminal may display a UI screen including information about whether the ship is likely to collide based on the information received from the server device 200. In particular, the user terminal may provide various types of warning notifications (eg, visual notification, auditory notification, haptic notification) when there is a possibility of ship collision.

According to one example, the processor 130 identifies the position, speed, ground speed, ground direction, and heading information of the vessel based on the AIS data stored in the memory 120, and transmits the identified information through the communication interface 110. It can be transmitted to at least one of a ship or a user terminal. Here, SOG (Speed of Ground) refers to the speed relative to the land, which may mean the speed of moving away from the land behind. The speed at which the ship is moving on the water may be different from the speed at which the ship actually moves. Ground speed refers to the speed at which the ship actually moves relative to the ground. Course of ground (COG) is the direction in which a ship actually travels with respect to the ground, and can be calculated by comparing the actual position of the ship at regular time intervals. Heading information (True Heading) may refer to the direction the bow of the ship is facing.

In this case, at least one of the ship or the user terminal may display a UI screen including status information of ships located within a specific range around the port based on information received from the server device 200. For example, the UI screen may provide status information on ships existing within a specific range around the port, including both ships entering or leaving the port.

According to one example, the processor 130 may calculate the distance, direction, etc. from the quay wall at which the ship must dock using the ship's location information (e.g., latitude and longitude information) in order to accurately dock the ship and prevent collisions. there is. For example, factors that affect the moving speed and direction of a ship during actual operation include waves, wind (wind direction, wind speed), current, and ship berthing force. The berthing force acting on the mooring facility due to the ship is calculated based on the berthing energy of the ship, and is changing as the ship becomes larger, becomes a dedicated vessel, and increases cargo volume. It is an absolute factor in determining the berthing force and is used for safe pilotage in the field. What you need to pay attention to is the docking speed. Berthing speed can generally be defined as the speed measured vertically at first contact with the pier. As ships become larger, the difference in horizontal distance between the bow and stern often exceeds 200 to 300 m, and considering that the vessel berthing speedometer (DAS), which is a berthing speed measuring instrument, can measure at least two points, the contact berthing speed in each direction of the bow and stern The berthing speed must be calculated by taking all into account. In general, assuming that the ship moves laterally and docks, the kinetic energy of the ship can be equal to E=1/2 (M*V^2).

The processor 130 calculates the berthing energy E of the ship by a kinetic method based on Equation 1 below, considering the energy absorbed by the insecticide when the ship actually berths, and based on the calculated berthing energy, the ship It is possible to identify whether there is a possibility of conflict.

In general, the berthing speed of a vessel takes into account the alignment of large vessels, the status of cargo, the location and structure of mooring facilities, weather and sea conditions, the presence and size of tugboats, etc., in accordance with the 'Port and Fishing Port Design Standards' of the Ministry of Oceans and Fisheries. The berthing speed can usually be set within 10 to 15 cm/s based on actual measurement data. However, if set to a value higher than 10 to 15 cm/s, there may be a safety margin to absorb berthing energy even if the pilot's berthing speed is somewhat fast.

According to one example, the processor 130 may calculate the real-time stopping distance of the ship and use the calculated real-time stopping distance during emergency coordination, including collision avoidance and avoiding dangerous substances. Here, the real-time stopping distance of the ship may be the reverse coasting force, which is one of the stopping coasting forces, and may be the distance until the ship comes to a standstill by moving backwards at full speed while the ship is moving forward. For example, the processor 130 may calculate the real-time stopping distance of the ship based on information such as the ship's speed, captain, ship width, and draft. Referring to FIGS. 4A and 4B, the captain of the ship is the horizontal length of the ship, and the ship width may mean the pure internal gap excluding the thickness of the steel plate at the front of the ship. Draft refers to the depth of the submerged portion of a ship when it is floating on water, generally the vertical distance from the water surface to the lowest part of the ship. In particular, full load draft may mean the vertical distance from the position where the water surface in the center of the ship closes to the bottom of the ship when the ship is fully loaded. Shortest stopping distance is one of the important factors along with turning ability in evaluating the maneuverability of a ship, and the characteristics of the shortest stopping distance of a ship must be carefully judged and used appropriately during navigation. Accordingly, the real-time stopping distance can be calculated and used for emergency adjustments, such as avoiding collision with other vessels or avoiding dangerous goods.

For example, maneuverability may be reduced in low draft conditions. Maneuvering performance is most affected by the main specifications of the ship: length, width, draft, and square ratio coefficient. The smaller the “length/width” and the larger the “width/draft,” the lower the steering performance. Accordingly, the smaller the draft, the larger the “width/draft”, so the lower the draft, the lower the handling performance may be. Additionally, if the shape of the ship is a V-shaped stern, steering performance may be reduced. Accordingly, the processor 130 can calculate the real-time stopping distance by taking into account the case where the steering performance is deteriorated, or use the case where the steering performance is deteriorated for control such as avoiding collision with other ships and avoiding dangerous substances.

As described above, the processor 130 implements a ship's steering motion prediction algorithm and can be used in the ship's collision detection and avoidance algorithm and monitoring system.

In addition, according to various embodiments, a marine environment-based ship sinking prevention system can be implemented by implementing deep learning-based data analysis and sinking algorithms using the ship's AIS information. In addition, by using the ship's AIS information, object images around the ship and a video analysis algorithm can be implemented and used to measure and predict the maritime environment in the sea area around the image-based operating ship. In addition, using the ship's AIS information, it can be applied to a real-time maritime environment and ship motion performance-based operating system based on optimal route generation, route monitoring technology, and additional resistance estimation.

FIGS. 5A and 5B are diagrams for explaining an example of AIS device implementation according to an embodiment.

Figure 5a is an example of an AIS device for a ship according to an example. For example, AIS information of a ship can be transmitted and received through a VHF channel, DSC channel, etc. Depending on the speed of the ship, the transmission period of the ship's AIS information may vary. For example, the transmission period of AIS information may be different when anchoring and sailing.

5B is an example of an AIS device for a coastal base station according to an example, which may transmit not only the coastal base station location information but also information on transponders within range of radio frequencies to the operation center (e.g., server device 100). In addition, the ship's AIS information can be received in real time from the ship's transponder and transmitted to the coastal base station operation center.
